Meredith (closing voiceover): Every pressurized system needs a relief valve. There has to be a way to reduce the stress, the tension, before it becomes too much to bare. There has to be a way to find relief because if the pressure doesn't find a way out, it will make one. It will explode. It's the pressure we put on ourselves that's the hardest to bare. The pressure to be better then we already are. The pressure to be better than we think we can be. It never ever lets up. It just builds and builds and builds.
